Molar mass Li2O = 7.0 x 2 + 16 => 30 g/mol
1 mole Li2O ---------- 30 g
( moles Li2O ) -------- 45.0 g
moles Li2O = 45.0 x 1 / 30
moles Li2O = 45.0 / 30
= 1.50 moles of Li2O

Answer:
Gram atomic mass of an element can be defined as the mass of one mole of atoms of a particular element. It is numerically equivalent to the value of the element's atomic mass unit but has its unit in grams.
Answer:
The volume will be 6, 67 L
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T:
P1xV1/T1 = P2 x V2/T2
V2= ((P1xV1/T1)xT2)/P2
V2=((1,5 atm x5 L/300K)x400K)/1,5 atm
V2=6, 67 L
